ERCuAl-A2 (Alum Bronze A2) TIG Rod Blue Demon

Aluminum Bronze A-2 (ERCuAl-A2) filler metal
is an intermediate-strength aluminum bronze
alloy used for welding aluminum bronze plate
fabrications and for joining dissimilar metals
such as cast iron, carbon steels, copper,
bronze and copper-nickel materials. It is
excellent for building up or overlaying metal
for wear and corrosion resistant surfaces.
Weld deposits exhibit high mechanical
properties, tensile strength, yield strength
and hardness.

Applications
• Marine maintenance and repair
• Wear surface reconstruction
• Casting repair
• Joining aluminum bronze of similar
composition
